if you read the php redme.txt properly then it will tell you to do this aswell....
add this to your httpd.conf
#for the cgi binary (you can use that one compiled with force cgi redirect too)
ScriptAlias /php4/ "C:/php/"
Action application/x-httpd-php4 "/php4/php.exe"
AddType application/x-httpd-php4 .php
and remove the crappy code tht you used, i also had the same prob, this should fix it!!!
